Description
The 804 relay was designed to switch overbed lights in Hospital environments by interfacing to the Patient handset contacts. It comprises a microcontroller based electronic latching circuit that switches a mechanical relay. It achieves reliable, interference free switching of Overbed lights including LED, CFL and Flourescent types.
The input is safety isolated from the volt free output 10 Amp contacts, type A. The microcontroller ensures that very short handset pulses (e.g. dropping the handset) are ignored, and very long pulses (e.g. a button locked on) cause no damage. It has been carefully designed to be easy for older or infirm patients to operate.
